Question
Which of the following is the group of derived units?
A. m, s, Pa 𝑎𝑛𝑑 Nm, s, Pa and N
B. Pa, N, m/s 𝑎𝑛𝑑 W
C. k, m, kg k, m, kg and s
D. kg, K, Pa 𝑎𝑛𝑑 N kg, K, Pa and N
Solution
The derived units are combinations of the seven base units from the International System of Units (SI). These base units are: meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd).
Let's analyze each option:
A. m (meter), s (second), Pa (Pascal), Nm (Newton meter), and N (Newton).
- Meter and second are base units, not derived.
- Pascal is a derived unit (kg/(m·s²)).
- Newton meter is a derived unit (kg·m²/s²).
- Newton is a derived unit (kg·m/s²).
B. Pa (Pascal), N (Newton), m/s (meter per second), W (Watt).
- All of these are derived units. Pascal is kg/(m·s²), Newton is kg·m/s², meter per second is m/s (a derived unit of speed), and Watt is kg·m²/s³.
C. k (kelvin), m (meter), kg (kilogram), s (second).
- Kelvin, meter, kilogram, and second are all base units, not derived.
D. kg (kilogram), K (kelvin), Pa (Pascal), N (Newton).
- Kilogram and kelvin are base units, not derived.
- Pascal and Newton are derived units.
So, the group of derived units is option B: Pa (Pascal), N (Newton), m/s (meter per second), and W (Watt).
